Partridge, St. Paul, Minn. Application November 12, 1934, Serial No. 752,600 4 Claims. (Cl. :l5-76) Itis an object of this compact and eicient machine for rap invention to provide a idly and thoroughly cleansing drinking glasses, tumblers and like small receptacles and tableware.

Other objects will appear and be more fully pointed out in the following specification and claims.

Referring to the accompanying illustrate the best form of my device ent known to me;

Fig. 2 is a part rear elevation and part vertical section through the casing of the machine;

Fig. 3 is an isometric View of the main clamp member Fig. 4 is a side elevation of the machine showing it in the operating position and mounted on sink or other receptacle for the washing fluid;

Fig. 5 is an isometric View illustra ting the main body of one of the rotary brushes;

Fig. 6 is a quarter section through oneof the rotary brush tips, and

Fig. 7 is a diagrammatic bottom view illustrating the operation of the rotary and stationary brushes on a pair of the receptacles to be cleansed. Y

The machine has a `pair of spaced, power-driven shafts pair of tumblers or likereceptacles parallel,

I and II carrying rotary brushes I2 adapted to t within the interior of a I3 to be cleansed. Rigidly mounted between and in parallel relation to the shafts I0 and shaft I4 carrying a stationary brush II is a third I for cleansing the exterior of the receptacles I3. All three brushes extend along their supporting shafts a sufficient distance to reach from tom to the top of the receptacles I3.

The shaft I4 is fixed on a removable the botcover I6 of a housing I1 containing driving connections between a power shaft I8 Iand the shaft s IIl and il. The shaft I8 projects from an electric mo- I3 which is supported'on the housing I1.

and II shaft I8 and secured to shafts Ill and II severally trained on the pulleys 2B and 2|, and 2U and 22,

as shown in Fig. 2.

The casing I'I is formed with a pair of lugs or ears 24 for pivotally connecting the motor and housing by the numeral 25. A pivot bolt 26 through perforations in the ears 24 and to a clamp member indicated generally extends through a bearing 21 (Fig. 3) formed on the clamp member 25., The edge of a sink, drainboard or other suitable support for the machine may be clamped between a jaw 28 formed on the clamp member and a clamp boltr29 threaded in the clamp member and having a wing head to facilitate manual operation. A rest 3|] is formed on the clamp member to support the motor in idle or inoperative position.

To facilitate moving the motor and brush assembly from inoperative to operative position, I provide parallel arms 3| which extend at opposite sides of the motor and are pivotally connected by a bolt 33 to opposite ends of bosses 32 (Fig. 3) formed on the clamp member 25. The free or rear end of thearms 3I are joined together by a handle 34 and each of the arms 3| is formed with anA elongated slot 35 to receive a stud 36 which projects from the side of the motor casing. One of these studs 36 projects from the outer face'of the arm 3| to engage the'plunger 3l of an electric switch 38. The switch 38 is connected in the current supply circuit for the motor I9 and is so constructed that the motor is started and operated when the switch plunger the motor is tilted to the operative position shown in Fig. 4, the stud 36 releases the plunger 31 to thereby close the switch and operate the motor.

To facilitate the repair or replacement of the rotary brushes I2 when they become worn, I prefer to construct them as indicated in Figs. 1, 5 and 6. Each brush head has a body portion 39 formed with a central bore to receive the shaft I0 or -II and a transverse slot 4I] communicating with the bore to receive a cross pin 4I projecting from the supporting shaft for establishing the driving connection between the shaft and brush body. The head portion 42 of the brush is separable from the body portion 39 and has a threaded bore to receive and engage a. threaded end of the shaft IU or II. Both the body and head portions of the brush are designed to have groups of bristles secured thereto in longitudinal slots 43 formed in ribs 44 extending longitudinally of the brush body and head. Each of jthese ribs is arranged to receive a row of bristles set in a strip or insert fastened in the slot' 43 by suitable means. The greatest wear takes place on the'head of the brush where it engages the bottom of the receptacles and my construction of the brush is such that the head portion may be quickly and easily removed for replacement or repair independently of the body portion of the brush.

In operation, a pair of the tumblers or other receptacles i3 to be cleansed are inverted upon the rotary brushes i2 with the machine in the idle position indicated in Fig. l, said brushes extending to the inner surfaces of the bottoms of the receptacles and the brush l5 engaging the exterior surfaces of both receptacles. Now, by grasping the two receptacles the motor forward and downward until the receptacles are partially or wholly submerged in the cleaning Huid or wash water, the motor is automatically started and the brushes 2 are rotated rapidly. The operator, by grasping the exterior of the receptacles retains them against rotation while the interior surfaces are quickly and thoroughly cleansed and then by partially releasing the gripping pressure, the rotary brushes are allowed to rotate the receptacles in the hands of the operator so that the exterior surfaces are'rotated and cleansed by contact with the stationary brush l5. After a few revolutions of the receptacles in the washing solution the machine is returned to its inoperative position where the switch 38 opens the circuit and the receptacles i3 are then removed from the brushes. It will be understood that the entire cleaning operation is performed quickly and easily, without danger of breaking the receptacles. Thus the machine is adapted for use in cleaning delicate glass and chinaware.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. A machine of the class described having in combination, a support, a motor movably attached to said support, means for securing said support on a container for cleaning uid, a shaft operatively connected to said motor, a cleaning member mounted on said shaft and formed to t within receptacles to be cleansed, said cleaning member being arranged to be submerged in cleaning iluid in said container and raised above the surface thereof by appropriate movement of said motor a switch in circuit with said motor for controlling the same and a member movable with said motor and positioned to engage said switch to start and stop said motor respectively upon movement of said cleaning member to and from submerged position.

i3 and tilting 2.
